ATX Form Factor
The board is designed with ATX form factor - the latest industry standard of
chassis. The ATX form factor is essentially a Baby-AT baseboard rotated 90
degrees within the chassis enclosure and a new mounting configuration for the
power supply. With these changes the processor is relocated away from the
expansion slots, allowing them all to hold full length add-in cards. ATX defines a
double height aperture to the rear of the chassis which can be used to host a wide
range of onboard I/O. Only the size and position of this aperture is defined,
allowing PC manufacturers to add new I/O features (e.g.; TV input, TV output,
joystick, modem, LAN, audio, etc.) to systems. This will help systems integra-
tors differentiate their products in the marketplace, and better meet your needs.
• By integrating more I/O down onto the board and better positioning the hard
drive and floppy connectors material cost of cables and add-in cards is reduced.
• By reducing the number of cables and components in the system, manufacturing
time and inventory holding costs are reduced and reliability will increase.
• By using an optimized power supply, it's possible to reduce cooling costs and
lower acoustical noise.
